The latest for kerry kennedy, on trial for driving while drugged. More than a year after she was pulled over for wreaking havoc on a highway, the daughter of robert kennedy was in court again yesterday, when the judge set a date for jury selection. Abc's gio benitez has the story. Reporter: Kerry kennedy was all-smiles when she walked out of court tuesday. Confidently telling reporters -- looking forward to trial. Reporter: A judge set a trial date for kennedy's drugged driving case. The daughter of robert f. Kennedy swerved into a tractor-trailer in july 2012 and fled the scene. She had no control of the car. She almost hit about five cars before she got off at the exit. Reporter: Following the accident, she said she mistakenly took the powerful sleeping drug ambien with her coffee that morning, instead of her thyroid medication. I want to apologize to the driver of the truck, who i apparently hit. And to all those I endangered. I remember getting on the highway. And then, I have no memory until I was stopped at a traffic light and a police officer was at my car door. Reporter: Police say the ex-wife of new york's governor, andrew cuomo, was slumped over her wheel, when officers found her off a new york highway, charging her with driving while impaired. She has pleaded not guilty. I think she's frustrated about the fact that the case has dragged on this long. She's anxious to put this behind her. She's anxious to have it tried. Reporter: In may, a judge dismissed the case, letting jurors decide whether she took the ambien mistakenly. Jurors get that chance when the trial begins in january. Gio benitez, abc news, new york.
